Xiao Yu'er saw it in her eyes, and her heart suddenly moved, and she secretly thought: It is said that the mother-in-law and daughter-in-law are not very good at dealing with each other, but Niu Er's old mother always speaks for her daughter-in-law, so there is nothing strange about the case, right?

Niu Er is sick and bedridden all the year round, and he may not be clear about his daughter-in-law's affairs, but this old woman is not deaf or blind, and it is difficult for her daughter-in-law to hide what she has done......

But thinking of this, Xiao Yu'er shook her head again, after all, the evidence is conclusive!

Silver needle tests don't react to most poisons, but silver is very sensitive to the most common form of arsenic and turns black when it comes into contact with it. (Please search Bayi Chinese Net, the fastest updated novel website!)

Arsenic is arsenic trioxide, which itself does not react with silver, but the ancient technology of refining arsenic is not mature, and the finished product contains a lot of sulfides.

Just now I put the silver needle into the mouth of the deceased, and when I pulled it out, it turned black, which everyone saw with their own eyes, and it could not be faked.

After thinking for a while, Xiao Yu'er beckoned to the two children with a smile on her face: "Come here, uncle has something to ask you." ”

The younger child shrank straight into his grandmother's arms, looking at Xiao Yu'er with an innocent face, but the older child was grateful that he had just kicked down the poor woman and obediently walked to his feet.

"Tell the truth with my brother, if you tell the truth, my brother can help your mother. And there are sugar gourds to eat. ”

"Let them not beat their mothers, okay?"

Xiao Yu'er nodded, and the child suddenly smiled: "Brother is really a good person." ”

Xiao Yu'er said step by step: "How does your mother usually treat your father, have you ever quarreled?" Has anyone else been in the house? ”

"Mother is kind to Daddy, she has never quarreled," the little boy tilted his head and thought for a while, "Someone has been here." ”

Xiao Yu'er's heart sank and asked who it was?

"It's you, brother!" The little boy looked at him very strangely, "You just came." ”

Everyone laughed from the side.

Xiao Yu'er blackened his face, patted the little boy's head, and asked the old woman to lead him.

Such a young child can't lie. Even if the old woman may have lied to her daughter-in-law for some other reason, the little boy's words are absolutely true.

So what went wrong?

Xiao Yu'er said: "Don't take it away yet." ”

Wang Chao said: "Do you have eyebrows? ”

"Not yet." Xiao Yu'er replied.

"Then hurry up, if the adults blame it, it's always bad." Wang Dynasty said.

Xiao Yu'er nodded, came to the coffin again, and took a closer look again.

It is true that there are no scars on the neck, and the swelling of the head and face can also be explained by the blood stasis caused by poor circulation of the cardiovascular system. But no matter how I look at it, I feel a little uncomfortable, and I always feel that there is something I didn't expect.

Suddenly thinking of a possibility, he was shocked, and quickly stretched out his finger to peel off the dead man's eyelids and observe them carefully.

I saw that there was already a layer of white puff on the eyeballs, which was blurry, and it was a little difficult to see in this poorly lit hall. Xiao Yu'er took out the fire fold from his pocket and shone it. Xiao Yu'er once again opened the dead man's eyelids, and finally the corners of his mouth showed some kind of meaningful smile-

In addition to the white pannus formed after death, under the conjunctiva of the deceased's eyes, there are scattered spots of bleeding!

The conjunctiva of the deceased had a significant number of hemorrhagic spots, but all were the size of a pinpoint and were confused by the white pannu that formed on the eyeball after death, if not with the help of a light source. I'm afraid that even the extremely experienced old man can't show up.

The conjunctiva of the eye is a translucent membrane rich in capillaries, and when the human neck is mechanically compressed, the pressure in these capillaries will rise sharply, and the permeability of the blood vessel wall will also increase due to the lack of oxygen in the victim, and the blood will seep out of the capillaries under the increased pressure, forming pinpoint-like bleeding points.

Although conjunctival hemorrhage cannot be 100% equated with mechanical asphyxia, it is not far from it.

The little fish grabbed the dead body's hand again. Very carefully examined, very attentive. Finally, Xiao Yu'er snorted coldly in her nose, put down the hand of the dead corpse, swept her eyes to the crowd, and smiled mockingly.

"Niu Er was not poisoned, but strangled to death." Xiao Yu'er said the conclusion.

Immediately, there was an uproar, and everyone's faces showed disbelief. Even the dynasty, which has always admired Xiao Yu'er, couldn't help but say: "Xiao Yu'er, isn't it wrong?" These eyes can't be mistaken, the silver needle has become black, and it is obvious that it has taken arsenic. But there is no trace on the neck, how can it be strangulation? ”

There was no scar on the neck of the corpse, which could not be more obvious, and the people also talked about it in their eyes, saying that Xiao Yu'er was afraid that he had lost his eyes this time.

Probably many people don't know much about Xiaoyuer, and some people shouted: "Isn't this talking nonsense with your eyes open?" Whether it is strangled or not, it can be seen at a glance, but the arsenic has been detected with a silver needle, and there is real evidence. He's a bully! ”

Someone said: "What kind of plague people, also come to mix up the insiders!" Don't fall in love with Little Widow, do you? ”

Xiao Yu'er's eyes were bright, and his expression was calm with a certain indescribable momentum, and the whole person was like a sharp sword out of the sheath. , said: "Folks, who is right and wrong, you will know later." So Xiao Yu'er took out a silver needle and said, "If the deceased was poisoned, then his whole body was covered with toxins, then this silver needle will turn black?" ”

"That's right." The crowd nodded.

Xiao Yu'er said to the dynasty: "Brother Wang, throw away the clothes of the deceased." ”

"What is this for?" Wang Chao asked strangely.

Xiao Yu'er said impatiently: "We'll know later." ”

The dynasty did so and threw his clothes away, revealing the upper body of the deceased. Xiao Yu'er poked the silver needle into the stomach of the deceased, and after a moment held it high, only to see that the silver needle was still as bright as new, shining in the sun for everyone to see very clearly. Dengshi's exclamation was ten times better than the first time a silver needle probed his throat.

Wang Chao was amazed: "The throat is poisonous, but the stomach is not poisonous, isn't it poison that is poured after death?" ”

The undertaker Zhou Donkey subconsciously wanted to escape, but when he turned around, he bumped into Mahan. Mahan was very unfriendly and said, "Where are you going?" Xiao Yu'er had instructed Mahan to pay attention to the surrounding crowd of onlookers, and the suspect was very willing to be inside. Why? Because the prisoner was very proud of his work.

"Me, me?" Zhou Donkey'er's face turned white, and he stammered: "I want to go to the thatched house?!" ”

"Clamp my legs and hold on." Mahan snapped.

Wang Chao asked, "Xiao Yu'er, how did the deceased die?" ”

Xiao Yu'er said: "The deceased was choked by the neck, in order to cover up this qiē, the deceased used a pillow or cloth to cover it, which naturally makes people feel it." ”

"Xiao Yu'er, who is the murderer?" Wang Chao asked. Everyone is also in line with the Tao, although they know that Niu Er was strangled to death instead of being poisoned, but what about the murderer?

Xiao Yu'er said: "The motive for killing is nothing more than a few points, one is vendetta, and the other is profit. Niu Er makes dim sum, and there is no possibility of vendetta, so the rest is to kill. ”

Wang Chao asked, "What is profit-killing?" ”

Xiao Yu'er replied: "It's profit, whoever is most beneficial to Niu Er's death is the murderer." ”

"So that's him?!" Ma Han pushed the undertaker Zhou Donkey out and said, "This person is suing, once it is confirmed that Niu Er was poisoned by arsenic, then he may get 1oo taels of silver." ”

Zhou Donkey's upper and lower teeth clucked, and he said in a trembling voice: "Wronged...... I didn't kill anyone...... I was wronged, how could I kill someone?

"Yes!" Wang Chaoyi slapped and said: "Zhou Donkey killed Niu Er, and then went to the state government to falsely accuse and frame Niu Er's sister-in-law, and after the case is closed, he can be rewarded by the government." Why use sophisticated methods of killing? Because direct strangulation would leave a handprint belonging to a man on the neck of the deceased, he could not frame Niu's second sister-in-law, so he put a pillow on it when committing the crime, leaving no obvious traces. But in this way, there are no obvious injuries on the surface of the corpse, and it looks like it has died of illness, and the government will definitely not agree to the autopsy, so he must pour arsenic into the mouth of the corpse, so that we can see it with a silver needle. ”

Oh ~ I see! Everyone "suddenly realized".

Zhou Donkey was angry and scolded: "You spew blood!" If I can strangle him, why not just poison him? Quietly ran to Niu Er's house and poisoned it, can't he also frame Niu Er's sister-in-law? ”

For a long time in the dynasty's mouth, he didn't say that he was ugly. Then call for help and the little fish.

Xiao Yu'er said: "Arsenic has a taste. "Originally, arsenic trioxide, the ingredient of arsenic, was colorless and odorless, but the ancient refining was impure and contained a large number of sulfide impurities, making it smell like rotten eggs, and it was still relatively easy to be recognized when used for poisoning - so to use arsenic to kill people is not as convenient and fast as the legend says.

Xiao Yu'er rescued the emergency, and the dynasty was grateful, and reinvigorated and said: "Arsenic smells of rotten eggs, and it is easy to be shown in the meal, as long as Zhou Donkey's crime is revealed, it will no longer be able to continue, so he uses the method of strangling first and then pouring arsenic." ”

After listening to the analysis of the dynasty, everyone felt that it made sense, and the officials shook the iron rope and were ready to lock up Zhou Donkey, and the head of the undertaker, who was about to take the bonus just now, had already shrunk on the ground and shook into a ball, and he couldn't stop crying wrong.

"Wait?!" Xiao Yu'er stopped again.
